From memory the Maverick's are screen printed directly onto wood - not vinyl (ie decals)...

To in reality, touchups are possible.  But - if for example you're doing the brown on the main body of the cabinet, I would suggest you would have to mask up all the detail work inside and spray the entire area in one hit.  Very difficult to get an exact match.  Once you've done it, you should clear the area for protection.  Not a small job.

Sometimes its better to leave it alone, as touchups can look worse!

Maybe post some pics of the areas your talking about to give us a better idea.
